I have succesfully moved the first exchange server (Mailserver) to a new server (Mailserver2) following the insructions in microsoft kb article q152959. My problem is I cant uninstall exchange 2000 on old server reports one or more users currently use a mailbox store on this server must be disabled or moved. The mailboxes in the store are SMTP and System attendant how do disable or move these mailboxes so that I can uninstall exchange 2000 on this server. Thanks, Alan.
